Allweiler® Pump Model Identification Directory
Identify supported Allweiler® progressive cavity pump models by series, nominal size, stage and type designation.
Start with the complete model shown on the pump nameplate, manual or drawing. Select the family below, verify the full designation and continue to the corresponding ACCA replacement-parts resource.
How to Use This Allweiler® Model Directory
This page is organized for model identification. It preserves established model designations while keeping replacement-component specifications on the dedicated Allweiler® parts pages.
Important: a family and nominal size alone do not identify every installed component. Always send the complete nameplate designation and photographs when requesting assistance.
Select Your Allweiler® Pump Family
Choose a family to reach its model list. Each family also links to its separate replacement-parts page, keeping model lookup and parts selection distinct.

Information Contained in an Allweiler® Type Code
| Identification Item | What to Record | Why It Matters |
|---|---|---|
| Series | SLP, SEP, SNP, SHP, SNZP, AE or TECFLOW | Routes the pump to the correct family documentation |
| Nominal size | Every number and separator exactly as shown | Distinguishes pumping-element geometry and capacity family |
| Stage designation | Final .1, .2, .3, .4 or compound arrangement | Affects available differential-pressure construction |
| System or construction letters | E, N, H, V, AEB1L or other displayed code | Can identify drive, mechanical arrangement or product generation |
| Connections and orientation | Flange standard, branch position and casing arrangement | Affects installation fit and casing selection |
| Seal and material codes | Packing or mechanical seal plus available material designations | Separates shaft-seal and wetted-component variants |
Cannot Identify the Complete Model?
A partial or damaged nameplate does not always prevent identification. Send the clearest available equipment information so ACCA can determine what additional measurements or documentation may be needed.
Allweiler® Model Identification Questions
Does the nominal size identify the complete pump?
No. The family, nominal size and stage are only part of the designation. Connections, seals, materials, orientation and design options may also affect the installed construction.
Why must punctuation in the model number be preserved?
Decimal points, commas and plus signs can separate nominal sizes, stage arrangements or construction variants. Record the nameplate exactly as shown.
Are TECFLOW and AEB1L related?
Manufacturer documentation identifies TECFLOW AEB1L as the compact block-design progressing cavity pump family. Use the complete installed type code for identification.
Can ACCA identify a pump from a photograph?
Photographs can narrow the family and construction, but dimensions, the complete model code, documentation or a physical sample may still be necessary.
Does inclusion in this directory guarantee every component is available?
No. The directory supports identification. Replacement availability is confirmed from the complete pump designation, requested component, dimensions and service conditions.
